1. Cement electric bending test machine uses:
Mainly used in cement plants, construction units and related professional schools It is used by scientific research units to test the flexural strength of cement soft-coated mortar, and can also be used to test the flexural strength of other non-metallic brittle materials.
The maximum test force of this testing machine when using a single lever is, and the maximum testing force when using a double lever is. The scale of the testing machine has a conversion scale specially designed for the flexural strength and flexural strength of cement soft tempered mortar. The maximum test force When the maximum test force is, the reading value is accurate to and. When the maximum test force is, the reading value is accurate to and.

3. Structure of cement electric flexural testing machine:
This testing machine has a base, a column, It consists of upper beam, long and short tie rods, large and small levers, lift angle indicator plate, anti-folding fixture, swimming weight, large and small balance thallium, transmission motor, transmission screw, and electrical control box.
4. Use, adjustment and maintenance of cement electric flexural testing machine:
This testing machine is placed directly on the platform for use in a vibration-free environment, and the platform must be calibrated (). When conducting tests within the resistance range (using a double lever), hang the anti-folding clamp on the middle blade of the small lever (as shown in Figure 1). If conducting tests within the resistance range (using a single lever), it must be removed. The small lever and the short pull rod () and force bearing () originally connected to the big lever () are connected to the big lever by the long pull rod () on the upper part of the clamp, and the lower part is unscrewed from the original position and screwed into the upper part. in the nut () on the base () at the relative position.
Before the test, first turn on the power, press the button () on the swimming weight, and push the swimming weight to the left by hand, so that the zero line of the upper vernier () of the swimming weight is aligned with the scale () The zero line, the aligned engraved line may move after releasing the button. At this time, you can use your hand to turn the screw rod on the knurled part on the right end of the screw rod and move the swimming weight to make the two zero lines coincide. Adjust the zero-setting contact screw () behind the lift angle indicator plate so that it just contacts the moving weight, and then tighten the zero-setting contact screw () with the nut () to calibrate the zero of the cursor () and the scale. Check whether the lines coincide with each other. If not, readjust the zero-setting contact screw and repeat the above adjustment until the cursor coincides with the zero line of the scale when the swimming weight and the zero-setting contact screw are just in contact.
Loosen the locking nuts () and (), move the large and small balance thallium, so that the large lever () is as balanced as possible, then tighten the locking screw, and lock the large balance thallium () on the large lever , move the nut () on the small balance thallium () to move the small balance thallium until the large lever is completely balanced, and then use the locking screw to lock the small balance thallium on the large lever. Pay attention to the locking of the large and small balance thallium. The tightening must be reliable to prevent the specimen from breaking during use and the large lever being vibrated when it falls, thus destroying the adjusted balance. Place the specimen into the anti-folding fixture, use the alignment plate () on the fixture to align it by hand and visual inspection, turn the handwheel () under the fixture to align the loading shaft () on the drop-down frame () with the specimen Contact, and continue to rotate at a certain angle so that the large lever has a certain lift angle. The data is determined based on the deformation of the specimen when it breaks. The principle is that when the specimen breaks, the large lever should be in a horizontal position as much as possible. The value of the lift angle can be determined by the lift angle. Read on the indicator board. (Each grid is) Press the start button on the electrical control box (), the motor () immediately turns the screw rod to push the swimming weight to move to the right, the machine begins to load, and the large lever gradually sinks. When the large lever is close to the level, When the test object breaks, the limit switch collision plate () at the right end of the large lever pushes the limit switch, cuts off the power of the motor, and the motor stops immediately. At this time, the test object resistance or The flexural strength value is the end of the test.
Press the button () to push the swimming weight to the left, reset the swimming weight, and then perform the second test.
The machine must be kept clean and dry during use. In particular, the blades and blade bearings must be prevented from rusting to avoid reducing sensitivity and accuracy. There should be no lubricating oil between the blade and the blade bearing to avoid dust sticking, blocking the lever movement and affecting sensitivity. The machine should be covered with a dust cover after use.
The limit switch strike plate on the right end of the large lever must be adjusted to the point where the limit switch just activates when the large lever drops to the bottom. Do not adjust the position to a position that activates the limit switch too early to avoid damaging the limit switch. The swimming weight for loading is on the lever. There should be no excessive left and right movement when the button is not pressed. If the swimming weight vibrates obviously on the screw after long-term use, the half nut can be replaced. If If necessary, please come to the factory to purchase.
When there is movement in the swimming weight, the solution can be solved as follows:
Just put some green shell paper on the bearing cap at the right end of the screw head.
